To all whom, it may concern.-

Be it known that l', ALFRED T. TREGUR- THA, of Everett, in the county of Middlesex and Stat-e of Massachusetts, have invented certain new and useful Improvements in Sole-Laying Machines, of which the following is a full, clear, and exact description.

This invention relates to a machine for the purpose of temporarily securing the outer Io sole to a lasted upper and in ner sole of a boot or shoe, for it afterward to be secured' by stitches or other fastening in the usual way; and the invention consists of a sole-laying machine constructed and arranged for operation, all substantially as hereinafter fully described.

ln the accompanying sheets of drawings is illustrated a soleelaying machine constructed inaccordance with this inventionzo Figure l being a side elevation; Fig. 2, a

front elevation; Fig. 3, a vertical central section from front to rear; Fig. 4, a detail plan view, to be hereinafter referred to; Fig. 5, a

detail plan view below line 5 5, Fig. 3. Fig. (i is 2 5 `a cross-section on line 6 6, Fig. l. Fig. 7 is a detail section on line 7 7, Fig. 3; and Fig. 8 is a Vdetail plan view. Fig. 9 is a detail plan view; and Figs. l0 and ll are detail front and side views, respectively, of one of the parts.

In the drawings, A represents two upright standards connected together by three horizontal eross-rods, B, C, and D, secured by setscrews ci, and on which are supported and carried the various parts of the machine.

E is a bed made of box shape, (shown in Fig. 3 in section,) and hinged at one end between arms F of the uprights A to the rod B, on which it can swing vertically.

G is a link pivoted by its forked arms ZJ to the back end of the bed box-frame, and by its other end, d, pivoted at e, between the two forked arms f of a lever, H, turning on the cross-rod C of the uprights, the portion g of this lever y extending to the front of the machine in an angular direction at one side and having' a handle, h, for operation thereof, as shown in Figs. l and 2 more particularly.v

J is a plate secured to the upright at the right of the lever H and having a series of 5,0 notches, m, arranged concentrically to the rod or pivot C, and adapted to engage with these notches is ai pin or pawl, K, arranged to slide in guideways n on and pivoted at q to the lever, and having an arm, r, against which bears a flat spring, t, secured to the handle h, the tension of which spring acts to hold the pin or pawl K to its engagement with the notched plate and thus hold the lever fastenedfrom movement.

Pressing the arm i" toward the lever-handle 6o moves the pawl K up and away from its en-` gagement with the notched plate, and then moving down the lever through its link-con nection G with the box-frame E will swing it down on its hinges into the position shown in dotted lines in liig. l, and when swung up into its normal position in full lines, Fig. l, the arm f of the lever and link G act as a togglejoint and hold the box-frame E firmly in'such position, the lever also interlocking with the 7o notched plate, preventing accidental move ment of the bedframe, and when the bed is in an intermediate position the engagement of the lever-pawl K with the notched plate sccures the lever and thus the bed in such position.

M is a cross-head rigidly attached to two vertical rods, N, arranged to slide up and down in sockets u, one in each upright A, and connected at their lower ends to another cross 8o bar or head, P.

On each rod N is a spiral spring, Q, bearingagailist the under side of the cross-head M and the upper end, fr, of its respective npright.

Pivoted at w to the bottom of the crosshead P is a link, R, in turn pivoted by its other end to one arm, S, of a lever or treadle, T, which is arranged to swing on the rod D, its other arm, U, projecting to the front in 9o convenient position for operation thereof by the foot. This lever is prevented from lateral movement on its rod or pivot by its abutment against the shoulder 0r of the upright and a collar, y, secured by set-screw .e to its rod D. 9 5

The pivot or pin cton which the link R swings passes through an` elongated slot, b', in one arm of the treadle T, and when adjusted to any position in such slot it is secured from movement therein by screwing up roo the check-nut c on the end of. said pin, having a handle, d. (Shown in 2 and '7.)

The treadle has foot-pieces V, pivoted at f', for it to swing thereon vertically within certain limits, and lirojecting therefrom is a steel pawl, lV, arran ged to en gage with n otches g in af bar, Y, secured to the iioor, the pawl, when the lever is pressed down, engaging with a notch and holding the lever from upward movement, and to free the lever from such engagement it is pressed down sufficiently to release the pawl from its engagement with the bar Y. Then swinging up the foot-piece,the treadle can freely rise. By pressing down this lever the cross-heads P S are pulled down against the springs Q, the rods N sliding freely in their sockets, and when the lever is released the springs act to raise them to their normal positions.

Attached to the upper cross-head, M, by a secliet, h, inthe head, and a ball, m, makiii-'g a ball-and-socket joint, is a jack or holder, Afor the last, made of a cross-arm, B",hav' ing downwardly-projecting arms C at each end, between which are pivoted, respectively, levers D E at n', the arms r t of which eX- teiid toward each other and each engages by a separate pin, u', witha horizontal slot, r, in a block or nut, F. The end of one of the arins of the levers E has a pin, c2, which is of a size to fit the usual socket in the heel of the last, and is pivoted to it by a bolt, w?, between two arms, m2, of the arm, on which bolt or pivot it can swing back and forth in line with the length of the last, and it has a plate, 'l1/2, extending up in front of the arm, having on its upper edge ratchet-teeth z2, arranged concentrically to said pivot, and arranged to engage with these ratchet-teeth by its end CL3 is a pawl, N,secnred to the side of the leverarm by a screw, P', which passes through a longitudinal slot, b3, and screws into theleverarm, as shown more particularly in Figs. l0 and ll. Turning out this screw, the pawl N can be raised and the pin c2 turned on its pivot to the right lor left to have it project from its supporting-arm in the angle desired, and then push the pawl down to engage a tooth and secure it by the screw l, which will hold the pin firmly and rigidly in such position on the lever-arm. The end of the downwardly-proj ectin g arm of the otherlever, D', has a pivoted toe-piece, F2, conca-ve on its under face, against which face the upper side of the toe of the last or the lasted npperbears when placed on the jack, as shown more particularly in Fig. l.

Passing freely through openings u in the shell forming the socket 7L is a stem or rod, G, which extends through and is arranged to turn freely in the ball in and prevented from longitudinal movement by the liange or shoulder CL2 on one end and by its other end by a loose sleeve, b2, on a reduced portion, d?, of v,the rod G, held by the nut c2 on the end of the rod above the handle or wheel H on the rod. This rod has a screw-thread on its lower end arranged to screw into the block or nut F, so that the turning of this screwrod to the right or left will raise or lower accordingly the nut F', and consequently t-he arms r i. of the levers D E', swinging them on their pivots correspondingly and moving` their lower arms to or from each other.

\Vithin the box E is a plate, J, preferably of spring metal-shaped longitudinally to conform substantially to the longitudinal conto ur of the bottom of the last or the lasted upper, and it is fastened near its right-hand end to a transverse rib, f2, of the bottom of the boX by screws g2, the plateotherwise being free within the box, so that its ends can freely move up and down. Screwing up through the bottom of the box, one at each end and one between the rib f2 and the left-hand one, are three screws, K', Q', and R, the one at the left adapted to screw up against the under side of the left-'hand end of the plate, andthe other two screws each having on its end Aa circumferential groove, c3, which engages with a shoulder, d3, on the inner side of a block, e3, secured to the under side of the plate J by screws f3. These screws are for adjusting the plate J s0 that it will conform to the 'various shapes longitudinally of the bottoms of the lasts or inner soles operated upon by the machine, and in their use the two screws Q R, as they are screwed up or down by their groove-connections c3 with the plates, respectively raise or lower the same at their respective connecting-points, and the screw K when screwed up, raises its end of the plate and TOO makes a rest or bearing for its end, so that with these several screws the plate J (being made of spring metal) can be brought to the desired outline or shape, corresponding to the varied outlines or shapes of the sole of the boot being operated upon. Jithin the bonr and resting on this plate J is a sheet ofiindia-rubber, L and resting 'on this sheetrof india-rubber are blocks M, made of indiarnbbersqnare in cross-section, all of the same length and size and filling' the box, as shown in section in Fig. 3 and in plan-view in Fig. 4, fitting, preferably, closely together within the box. On top of these india-rubber blocks is a sheet or layer of felt, N.

l 'lhc operation of the machine is as follows: The lever ll is first swung down so as to bring the boxE down into the position shown `in dotted lines in Fig. l, and the screw G turned to the left to swing the lower arms of the levers from cach other; loosen the pawl N on the lever E', so its pin c2 can freely swing on its pivot, and then place the socket at the heel of the last with the lasted upper thereon on the pin, and turn the screwrod G to the right, which will swing the l. The treadle T is now pressed down,which, i

through its connections with the cross-heads H N, draws down the jaclethe outer sole t-hen bearing upon theupper felt sheet above the india-rubber blocks, and with sufficient power exerted upon the treadle T the yielding indiarubber blocks will press the outer sole closely at all points to the bottom of the inner sole, according to the contourof the inner sole, the

jack or holder ot the boot or shoe, through its ball-and-socket joint, allowing Jthe jack to move, swing, and adjust itself to the yielding .bed of blocks, so that all points of the surfaces Vot the two soles will be properly secured together. by the cement. Then the cement is sufficiently set or dry, the treadle is allowed to rise, which raises the jack and its boot or shoe 4from its yielding bed, whi'ch then is swung down by operating its lever H, the screw G turned to tree the last; from the levers D E', whieh,with the boot or shoe, can be removed trom the jack or holder and another put in'` place, and its out-cr sole secured as before, and so on. The swingingdown of the bed-frame gives plenty of room between it and the jack tor the easy and conveniel'it removal of the last and boot lrom the jack; also, it can be arranged to swing in other ways than as herein particularly shown. It is prevented Afrom lateral movement by its hinges l; bearing against the collars ol' the rod B.

lf desirous olf j'nessing any portion ot the outer sole harder than at other points to inn sure its close union at such points with the inner sole, the plate J can be raised at such portion byturnin up or in the several screws K Q R', by which more pressure will be exerted upon 'the outer sole at such place l'i om the same downward movement of the jack, these screws, as they are turned in or out., correspomlingly raising or lowering the portion of the plate to which they arc att-aehetil,

the circumferential grooves in the screws Q and R allowing otf their being freely turned in either direction. This plate, however, can be dispensed with and the bottom ot the box shaped to conform to the bottom of the boot or shoe vfor thc yielding blocks to lsreil,to exert more pressure upon the'sole at one end or the other; also in lieu ot tastening the plate at the point shown to the bedbottom it can be fastened at either end, as

desired, and in such case the location of the screws K Q R would be correspondingly changed and arranged to suit; and, it' desired, a more or less number of screws can be used, as desired.

Each elastic block hl in its operation yields parts, fr2 t2, 'for the insertion of the ball, secured together by screws u2, as shown in Figs.

2 and 5.

In lieu oi' having the rod or spindle G screw into the block It", it can be arranged to screw into the ball and turn freely in the block and be provided with shoulders to prevent longitudinal movement of the rod; also, in lieu ot' having both levers of the jack swing on their '-pivots, one can be rigid, and they can be adjusted and arranged for operation in other ways than as shown. l

By means ot' the eloiigated sloth inthe arm. S of the treadle VT the pin a can be moved and adjusted asV to its distance from the fulcrum-pin u', so that the power of the treadle can be incl-eased.ordiminished, as desired, and the distance the jack is raised above the yielding bed; also, the link can be adjustabl y connected to the treadle in other ways than as herein particularly shown and described.

The sheet ot' telt prevents cement getting on the blocks to interfere with their proper movements.

The screws Q and R can be connected to the plate J in any suitable manner other than the particular one shown, so that they can turn freely and yet move up or down the plate, as desired.

Havin thus described my invention, whatl claim isl. ln a soledayng machine, a molding or pressure bed hinged at the toe end to a suitable support and having a tiogglelever pivoted to its oppositie end, and suitable means for operating said toggle-lever `for swinging said bed up and down and rigidly securing'it IOO ITO
